disclbsed.;,a: preferred embodiment: invention;- thevnumerali [ll represents -hollow throughout which is remoigfably secured to a substantially cylindrical extension [2 by means of a coupling ring l4.

Integrally formed with extension l2 adjacent its lower end is an annular ring or; boss l6 provided withian inclined upper sur' ce l8. Circumferentially spaced brackets 20 a1e carried by this ring and support roller bearings 22;

55 "drill pipe [0, and pipe 50 is raised on the pipe remain vertical when rotating and will also tend on the vane 38 with great force and this fluid will follow the contours of the vane which will rotate housing 34, bushing 26 and pipe section 50. This procedure will impart a rotary motion to the drill bit.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the claimed as new is:

Y 1. A deep well drilling apparatus comprising a drill pipe, a hollow extension therefor, a coupling member disposed between said pipe and said extension, a casing loosely embracing said coupling member, a bearing member loosely embracing said extension and supporting the casing,

a housing carried by said bearing member, and a plurality of spiral vanes mounted, in said housing for imparting rotary motion to the drill upon being contacted by a fluid forced through the pipe into said housing.

2. A deep well drilling apparatus comprising av pipev into said housing, and means carried by said, housing for engaging a drill'bit.

3. A deep well drilling apparatus comprising a drill pipe, a hollow extension removably secured to said drill pipe, a pipe section embracing adjacent portions of said drill pipe and said extension, a cap carried by said pipe section, bearings carried by said cap interposed between said pipe section and said dril1 pipe, a bearing member embracing said extension and supporting said pipe section, fiurther bearings between said ex-' tension and said bearing member, a housing carinvention, what isried by said bearing member and a plurality of spiral vanes mounted in said housing for imparting a rotary motion to said housing, said bearing member, and said pipe section upon being contacted by a fluid forced through the drill pipe and extension.

4. A deep well drilling apparatus comprising a drill pipe, a hollow extension removably secured to saiddrill pipe, a pipe section embracing adjacent portions of said drill pipe and said extension, a cap carried by said pipe section, bearings carried by said cap interposed between said pipe section and said drill pipe, a bearing member embracing said extension and supporting said pipe section, said bearing member having an inclined inner face, an annular ring integrally formed with saidextension having an inclined upper, face spaced parallel to the inclined inner face of said bearing member, further bearings interposed between said inclined faces, a housing carried by said bearing member, and a plurality of spiral vanes'mounted in said housing for imparting. a rotary motion to said housing, said bearing-member, and said pipe section upon being contacted by a' fluid forced through the drill pipe and extension. I

5. A deep well drilling apparatus comprising a drill pipe, a hollow extension, means coupling said extension to said drill pipe, an annular ring integrally formed with said'extension having an inclined bearing surface, a bearing member em'- bracing the .lower'portion of said extension and having an outer bearing surface and an inner bearing surface, said inner bearing surface being spaced parallel tosaid inclined bearing surface, bearings between said inner bearing surface and said inclined bearing surface," an upper pipe section embracing said drill pipe and said coupling means, said pipe section including a lower bearing edgeengaging the outer bearing surface of said member, said pipe section being slidable on said drill pipe for accessibility to said coupling means, a cap carried by the upper end of said pipe section, further bearings carried by said cap engaging said drill-pipe, a housing carried by said bearing member, and a plurality of spiral vanes mountedin said housing for imparting a rotary'motion to said pipe section, said housing and said bearing member upon being contacted by a fl uid forced through the drill pipe and extension.
